Frequently Asked Questions
Is this a real phone number or VoIP?

What can I use the number for?
Your number works for voice calls, sending and receiving SMS, iMessage, WhatsApp, and other messaging apps. Note that some third-party services may have their own restrictions on which numbers they accept.
What network does this use?
These eSIMs operate on T-Mobile's 5G network, providing 5G/LTE coverage across the United States with excellent coverage in most areas.

Note: The assigned number may be from various regions.
Can I make international calls?

How long do I have to activate the eSIM?
You have 12 months from purchase to install and activate it. The validity period only starts when the eSIM first connects to a network, so you can buy now and activate whenever you need it.
